a9795f81e9 Addition of the PPC32 Pattern ISel. While it is far from complete, it will 
be brought up to parity with the current simple ISel in the coming days.
Currently, -pattern-isel is required to trigger it.

e3f1d8a525 Totally gut mergeInGraph. There is absolutely no reason to be merging 
global roots in from callees to callers.  The BU graphs do not have accurate
globals information and all of the clients know it.  Instead, just make sure
the GG is up-to-date, and they will be perfectly satiated.

This speeds up the BU pass on 176.gcc from 5.5s to 1.5s, and Loc+BU+TD
from 7s to 2.7s.

1e9d1475bc Several changes here: 
1. Increase max node size from 64->256 to avoid collapsing an important
   structure in 181.mcf
2. If we have multiple calls to an indirect call node with an indirect
   callee, fold these call nodes together, to avoid DSA turning apoc into
   a flaming fireball of death when analyzing 176.gcc.
  With this change, 176.gcc now takes ~7s to analyze for loc+bu+td, with
  5.7s of that in the BU pass.

9308a35532 When making a clone of a DSGraph from the BU pass, make sure to remember that 
this clone is supposed to be used for *ALL* of the functions in the SCC.

This fixes the memory explosion problem the TD pass was having, reducing the
memory growth from 24MB -> 3.5MB on povray and 270MB ->8.3MB on perlbmk!
This obviously also speeds up the TD pass *a lot*.

3bc703ba22 Don't use operator[], use the new method instead, which is faster. This speeds 
up the TD pass about 30% for povray and perlbmk.  It's still not clear why
copying a 5MB set of graphs turns into a 25MB set of graphs though :(

275b301740 Enhance the TD pass to build composite graphs when we have indirect call 
sites that target multiple callees.  If we have a function table, for
example, with N callees, and M callers call through it, we used to have
to perform O(M*N) graph inlinings.  Now we perform O(M+N) inlinings.

This speeds up the td pass on perlbmk from 36.26s to 25.75s.

355ad1f3af Remove a bunch of cruft and dead code for handling the case when types were 
defined in function constant pools.  The assembler grammar has long
disallowed functions from having constant pools, so all of this stuff is
dead.

This makes it an immediate error for functions to refer to nonexisting
types, fixing Regression/Verifier/2005-03-21-UndefinedTypeReference.ll.

Before, references to non-existing types in functions would only be
detected when the subsequent function was parsed, due to the call to
"ResolveTypes".  "ResolveTypes" has not resolved any types for a long time,
instead it emitted an error message if no resolved types are left.  Since
the only caller of this method is in the module code, just inline it.

d57e55ec0d Change the way that the TD pass inlines graphs. Instead of inlining each 
graph into all of the functions it calls when we visit a graph, change it so
that the graph visitor inlines all of the callers of a graph into the current
graph when it visits it.

While we're at it, inline global information from the GG instead of from each
of the callers.  The GG contains a superset of the info that the callers do
anyway, and this way we only need to do it one time (not one for each caller).

This speeds up the TD pass substantially on several programs, and there is
still room for improvement.  For example, the TD pass used to take 147s
on perlbmk, it now takes 36s.  On povray, we went from about 5s to 1.97s.
134.perl is down from ~1s for Loc+BU+TD to .6s.

The TD pass needs a lot of improvement though, which will occur with later
patches.

9b426bdd81 Build EC's for globals twice. The first is after constructing the initial 
Globals Graph for the local pass, the second is after all of the locals
graphs have been constructed.  This allows for many additional global EC's
to be recognized that weren't before.  This speeds up analysis of programs
like 177.mesa, where it changes DSA from taking 0.712s to 0.4018s.

f4f6227989 Create an equivalence class of global variables that DSA will never be able 
to tell apart anyway, and only track the leader for of these equivalence
classes in our graphs.

This dramatically reduces the number of GlobalValue*'s that appear in scalar
maps, which A) reduces memory usage, by eliminating many many scalarmap entries
and B) reduces time for operations that need to execute an operation for each
global in the scalar map.

As an example, this reduces the memory used to analyze 176.gcc from 1GB to
511MB, which (while it's still way too much) is better because it doesn't hit
swap anymore.  On eon, this shrinks the local graphs from 14MB to 6.8MB,
shrinks the bu+td graphs of povray from 50M to 40M, shrinks the TD graphs of
130.li from 8.8M to 3.6M, etc.

This change also speeds up DSA on large programs where this makes a big
difference.  For example, 130.li goes from 1.17s -> 0.56s, 134.perl goes
from 2.14 -> 0.93s, povray goes from 15.63s->7.99s (!!!).

This also apparently either fixes the problem that caused DSA to crash on
perlbmk and gcc, or it hides it, because DSA now works on these.  These
both take entirely too much time in the TD pass (147s for perl, 538s for
gcc, vs 7.67/5.9s in the bu pass for either one), but this is a known
problem that I'll deal with later.

5021b8c2d6 do not bother inlining nullary functions without return values. The only 
effect these calls can have is due to global variables, and these passes
all use the globals graph to capture their effect anyway.  This speeds up
the BU pass very slightly on perlbmk, reducing the number of dsnodes
allocated from 98913 to 96423.

511f60c707 Rewrite DSAA::getModRefInfo to compute the mapping between caller and callee 
to determine mod/ref behavior, instead of creating a *copy* of the caller
graph and inlining the callee graph into the copy.

This speeds up aa-eval on Ptrdist/yacr2 from 109.13s to 3.98s, and gives
identical results.  The speedup is similar on other programs.

f768bba43f Allow the live interval analysis pass to be a bit more aggressive about 
numbering values in live ranges for physical registers.

The alpha backend currently generates code that looks like this:

  vreg = preg
...
  preg = vreg
  use preg
...
  preg = vreg
  use preg

etc.  Because vreg contains the value of preg coming in, each of the
copies back into preg contain that initial value as well.

In the case of the Alpha, this allows this testcase:

void "foo"(int %blah) {
        store int 5, int *%MyVar
        store int 12, int* %MyVar2
        ret void
}

to compile to:

foo:
        ldgp $29, 0($27)
        ldiq $0,5
        stl $0,MyVar
        ldiq $0,12
        stl $0,MyVar2
        ret $31,($26),1

instead of:

foo:
        ldgp $29, 0($27)
        bis $29,$29,$0
        ldiq $1,5
        bis $0,$0,$29
        stl $1,MyVar
        ldiq $1,12
        bis $0,$0,$29
        stl $1,MyVar2
        ret $31,($26),1

This does not seem to have any noticable effect on X86 code.

This fixes PR535.

14723c264d constant fold FP_ROUND_INREG, ZERO_EXTEND_INREG, and SIGN_EXTEND_INREG 
This allows the alpha backend to compile:

bool %test(uint %P) {
        %c = seteq uint %P, 0
        ret bool %c
}

into:

test:
        ldgp $29, 0($27)
        ZAP $16,240,$0
        CMPEQ $0,0,$0
        AND $0,1,$0
        ret $31,($26),1

instead of:

test:
        ldgp $29, 0($27)
        ZAP $16,240,$0
        ldiq $1,0
        ZAP $1,240,$1
        CMPEQ $0,$1,$0
        AND $0,1,$0
        ret $31,($26),1

... and fixes PR534.
